Overview

App Health Monitor is a client-side monitoring component for OutSystems Reactive apps. It tracks errors, slow calls, performance issues, and memory usage in real time — all from a single Client Action call.

Installation

Install the AppHealthMonitorCW module from Forge
Add a reference to LogInit Client Action in your app
Done

Setup

In your app's OnApplicationReady event, call LogInit:

Parameter	Type	Default	Description
`EspaceName`	Text		Your app name. Pass `GetEntryEspaceName()`
`BufferSize`	Integer	20	Logs to buffer before saving to server
`SLOW_THRESHOLD`	Integer	2000	REST call slow limit (ms)
`PERF_THRESHOLD`	Integer	3000	Screen load slow limit (ms)
`NAV_THRESHOLD`	Integer	30000	Long screen session limit (ms)
`MEM_THRESHOLD`	Integer	50	Memory warning limit (MB)

What Gets Logged

Type	When
`REST`	HTTP call fails (400+)
`SLOW`	Call duration exceeds SLOW_THRESHOLD
`ERR`	JS errors, console.error, unhandled promises
`WARN`	console. warn
`LOG`	console.log (OutSystems internal logs skipped)
`PERF`	Screen load exceeds PERF_THRESHOLD
`NAV`	User stays on screen beyond NAV_THRESHOLD
`MEM`	Memory exceeds MEM_THRESHOLD

Notes

All logs are buffered client-side in a Client Variable
Server sync happens automatically after BufferSize entries
OutSystems internal logs are automatically filtered from LOG type
Only problems are logged — successful fast calls are skipped
